A customer arrived with a brand new, frame and swing-arm from Cornish specialist Faber and asked the Boretech team to custom build a Triumph special to a spec that would qualify for classic events. So, we sourced a 1968 Triumph T100 engine and the new build began.
The engine was completely stripped, cleaned and shot blasted. The crankcases were fitted with new bearings and seals and the crankshaft, cylinder head and cylinders moved to the Boretech Engineering department where the crankshaft was reground and fitted with new big end shells and con rods. The cylinders were re-bored and the cylinder head had new valve seats cut, refaced and new valves fitted. The engine was repainted and the outer cases polished in-house. Then it was all reassembled ready to fit into the Faber frame.
As the customer only supplied the frame, swingarm and fork clamps, the Boretech engineering department made the wheel spindles, brake rod arms, engine brackets and all the spacers.
With the rebuilt engine in the frame, a full electronic ignition system was fitted along with a new Amal 900 series Concentric carb, breathing through a Twin-Air filter housed in a custom-made Boretech air box.
On the chassis side, new DID alloy rims were laced onto BSA style conical hubs and fitted with Michelin tyres. Betor front forks were fitted with Boretech's own valve system for improved damping, and the customer-supplied rear shocks also re-valved in-house. Boretech’s own 520 chain and sprocket kit conversion was also fitted.
As the customer wanted to race the bike, Boretech made the control cables in-house to fit a later type throttle assembly and lever controls. This makes it much easier to replace the parts after the inevitable slip-off, but still keeps an 'Old School' look.
The bike was then finished off with aluminium fenders, side plates and fuel tank painted in candy apple red.

The Suzuki was in reasonable overall condition, but the owner wanted a general service and clean-up to get it race ready and looking good without going to a total rebuild.
A new set of piston rings was fitted, but the bore and piston were in good condition, and all of the other engine and transmission parts were also within tolerance, so a fresh measure of Rock Oil GRO high-performance transmission oil was all that was needed to keep it running sweet.
A general race prep and detailing with new control levers and lubricated cables and brake service, plus a new set of tyres and decals topped it all off as you can see from the above picture.
